An apparatus adapted for use in the processing of a material traveling in a material direction, such as a photosensitive material. The apparatus directs a first fluid stream and a second fluid stream respectively across the first and second width portions of the material. The first and second fluid streams do not flow substantially cocurrently with nor countercurrently to the material direction.

Processing apparatus, method, and system for photosensitive materials

Flexible, photosensitive sheet material such as photographic film is processed for development through an apparatus comprising one or more cells, each having top and bottom plates in matched assembly to provide a thin film transit channel therebetween. Transverse of the film transit direction, fluid channel serrations are provided in top, bottom or both plates between developer solution supply and extraction manifolds.

Method and apparatus for processing photosensitive sheet material

A method for processing a flexible photosensitive sheet or web material (PSM) including a photographic emulsion on at least one of the flat surfaces thereof and employing a minimum quantity of processing solution including the steps of containing the processing solution in a generally sheet-like geometry, introducing the PSM into the processing solution at a liner face thereof, and substantially immediately upon the entry of the PSM into the processing solution, effecting dispersal of the processing solution onto the emulsion-bearing surface and retaining the solution on such surface for a period of time sufficient to render the surface susceptible to the flow and retention of the processing solution on such surface without external aid. Within the reservoir, the emulsion-bearing surface may be further subjected to one or more further treatments to enhance the development process.

Method and apparatus for the processing of a photosensitive sheet

A system and method for generating and codifying cropping and enlargement information for a rectangular photograph utilizes at least one transparent overlay and a grid board for underlying the overlay. The overlay includes markings providing a plurality of rectangular windows arranged about a common center and identification indicia for identifying each window and the enlargement multiple necessary to enlarge the window to a predetermined photo size. The grid board has a flat surface bearing a pair of intersecting lines which divide the surface into four quadrants about the center of the board surface, and one quadrant of the board bears a pattern of markings which provides the one quadrant with a two-coordinate grid and indicia for identifying coordinate locations on the grid. To use the system, the transparent overlay is positioned over the board so that the common center of the windows overlies the center of the board and then the photo is manipulated between the overlay and the board surface until the preselected area of the photo desired to be enlarged is suitably framed by a chosen one of the rectangular windows. By noting the identification indicia corresponding to the chosen window and the location on the board grid overlain by a corner of the photo, one possesses sufficient information to accurately isolate the selected area of the photo at a later time for enlargement purposes.
